Viber is designed for the iPhone/iPod touch and can be downloaded now on the App Store for free. It has yet to be fully optimized for the higher resolution handsets of the iPhone 6 and iPhone 6 Plus. Hopefully, that will arrive sooner rather than later.

The last major update to the app, before today’s improvements, arrived in early September. Along with the ability to add friends using the Viber numbers or QR codes, version 5.0 brought video calling for iOS users.
